Background technology
The characteristics of fingerprint identification device is different using the fingerprint tool of people carries out a kind of precise electronic of identification
Instrument, fingerprint collecting and to read be the most basic function of fingerprint identification device, and be fingerprint on the process nature of fingerprint collecting into
The process of picture.Fingerprint collecting is according to the difference of the geometrical property of finger asperities shape, physical features and biological nature, to obtain
Different optics or current resistor feedback signal, according to the value of feedback signal using the image processing algorithm of algorithms of different come
Plot fingerprint image.
Fingerprint identification device realizes fingerprint collecting by fingerprint sensor, and currently used fingerprint sensor includes optics
Fingerprint sensor and semiconductor fingerprint sensor, wherein：Optical fingerprint sensor realizes fingerprint collecting, light by optical imagery
The glass surface for being pressed with fingerprint is shone, reflection light is picked up by cmos sensor, so as to obtain fingerprint image；Semiconductor fingerprint passes
Sensor is mainly the collection that fingerprint image is realized using principles such as electric capacity, inductance, temperature or pressure.Optical fingerprint sensor is to dirty
Finger and dry finger surface have that the Fingerprint recognition rate of covering is very low, poor to the adaptability of the environmental factors such as temperature, and
The difficult situation of IMAQ occurs in semiconductor fingerprint sensor under wet hand state, causes recognition success rate not high.
The fingerprint identification device with single fingerprint sensor is difficult in the fingerprint recognition of dry, wet hand in the prior art
With high recognition success rate, solution commonly used in the prior art is in fingerprint identification device while sets optical finger print to pass
Sensor and semiconductor fingerprint sensor, a kind of fingerprint identification device as disclosed in Chinese patent literature CN201638241U, collection
Switched in turn using optical fingerprint collector and semiconductor fingerprint collector during fingerprint, it is ensured that the identification success of dry, wet finger line
Rate, but the cost increase of fingerprint identification device, and collection fingerprint is both needed to repeatedly switch between two sensors every time, not only influences dry
The fingerprint recognition success rate of hand, also reduce the whole efficiency of fingerprint recognition.
In view of this, one kind is needed badly to be respectively provided with high recognition success rate to dry, wet finger line, cost and tool need not be significantly increased
There is the fingerprint identification device compared with high workload efficiency.
The content of the invention
In order to solve the above technical problems, the embodiments of the invention provide a kind of fingerprint identification device, need not be significantly increased
On the premise of fingerprint sensor cost, can greatly it be improved under wet hand state while dry finger line recognition success rate is ensured
Fingerprint recognition success rate.
To realize above-mentioned technical purpose, the technical scheme that one embodiment of the invention provides is：
A kind of fingerprint identification device, including a fingerprint sensor, the fingerprint sensor are provided with fingerprint collecting window, institute
The surface pattern that fingerprint collecting window surface is provided with depression is stated, heater is provided with below the fingerprint collecting window.
Preferably, the surface pattern cross section is semicircle or trapezoidal or the two combination, also may be selected to be arranged to other
With respect to the shape of cross section that fingerprint collecting window is spill.
Another embodiment of the present invention additionally provides a kind of mobile terminal device, and the mobile terminal device includes described above
Fingerprint identification device.
The fingerprint collecting window that the above-mentioned technical proposal of the embodiment of the present invention passes through the fingerprint sensor in fingerprint identification device
Trickle surface pattern is provided with mouth, and heater is set below fingerprint collecting window, carries out wet hand during fingerprint recognition
Moisture on finger can be drained and be oven-dried from fingerprint collecting window surface by surface pattern, and its advantage is：Can be great
The fingerprint recognition success rate under wet hand state is improved, when being equally applicable to dry hand fingerprint recognition, and fingerprint sensor need not be set up,
Sensor cost is saved；Meanwhile it also ensure that fingerprint recognition efficiency without switching between multiple fingerprint sensors.

Embodiment
To make the technical problem to be solved in the present invention, technical scheme and advantage clearer, below in conjunction with accompanying drawing and tool
Body embodiment is described in detail.
The present invention be directed to existing technical problem, there is provided a kind of fingerprint identification device and mobile terminal device, by
Trickle surface pattern is provided with fingerprint identification device on the fingerprint collecting window of fingerprint sensor, and in fingerprint collecting window
Lower section sets heater, can be formed by the moisture on the wet finger of fingerprint collecting window by surface pattern during fingerprint recognition
Open pipeline drain and be oven-dried from fingerprint collecting window surface.
The fingerprint identification device of the present embodiment is as shown in figure 1, including a fingerprint sensor 1, the fingerprint sensor 1 is set
There is fingerprint collecting window 2, the surface of fingerprint collecting window 2 is provided with the surface pattern 3 of depression；The fingerprint collecting window 2
Lower section is provided with heater 5.The position of surface pattern 3 forms open pipeline 4 in the surface depressions of fingerprint collecting window 2,
When wet finger is pressed on the surface of fingerprint collecting window 2, because the pipeline of surface pattern 3 acts on, it can make it that finger surface is more
Remaining moisture is extruded into the open pipeline 4 of the formation of surface pattern 3, and moisture is extruded into fingerprint by open pipeline 4
The outside of acquisition window 2；And the moisture resided in surface pattern 3 passes through adding for the heater 5 below fingerprint collecting window 2
Heat is oven-dried, and can greatly lift the fingerprint recognition success rate of wet hand；And when carrying out fingerprint recognition to dry hand, with common finger
Line identification working method is similar, it may have meets the recognition success rate of needs.
As shown in Fig. 2 left side is the surface of the fingerprint collecting window in existing fingerprint identification device, after right side is improves
The surface signal of the fingerprint collecting window 2 after two kinds of different trickle surface patterns 3 is added, surface pattern 3 is overall to be in
